Simple conversion

Using FEZ Panda II hardware.

Below is a code fragment showing a byte array with an ASCII “O”, “K”, return, and some 0’s.

What would I need to replace the *** in the print argument below so that it would output OK.

…
byte[] rx_data = new byte[10] {79,75,13,0,0,0,0,0,0,0};
…
Debug.Print(***);

Not tested

Debug(new String(System.Text.Encoding.UTF8.GetChars(buf, 0, 3)));

Tried several variations. Generates an error indicating “cannot implicitly convert type ‘char[]’ to ‘string’.”

There’s a GetString method shown in the MS docs for the Encoding class but it doesn’t seem to be present. I don’t know what that means.Am I missing a namespace reference or ‘using’ statement. Encoding.GetChars(byte[]) is there but it doesn’t seem to like the argument.

Please include the specific code that is giving you an error.

The three last lines below were all underlined in red in the IDE starting after the ‘=’.

string OStr;
byte[] rx_data = new byte[10] {79,75,13,0,0,0,0,0,0,0};
…
OStr=System.Text.Encoding.UTF8.GetChars(rx_data);
OStr=System.Text.Encoding.UTF8.GetChars(rx_data,0,3);
OStr=System.Text.Encoding.UTF8.GetChars(rx_data[]);

GetChars() returns a char[] not a string.

As suggested earlier:

OStr= new String(System.Text.Encoding.UTF8.GetChars(rx_data));

This works good



            byte[] buf = new byte[10] { 79, 75, 13, 0, 0, 0, 0, 0, 0, 0 };
            Debug.Print(new String(System.Text.Encoding.UTF8.GetChars(buf)));

sorry Mike we were replying in parallel :slight_smile:

Thanks guys. I see that my problem was that I never instantiated OStr (left off the ‘new’). The problem with being new to C#.
